PC Video Card That Will Bitstream All Audio Sampling Rates Over HDMI

I use Foobar to bitstream audio from a desktop PC to a Yamaha receiver via HDMI. The NVIDIA GTX 745 video card in the PC does not support 88.1 kHz or 176.4 kHz audio files for bitstreaming(see quote from website below)

My AMD/ATI cards supported those frequencies but last one I used was the 7770, before that the 5000 series, and I think the 4000 series also supported those frequencies, but not bitstreaming of TrueHD/DTS-HD. NV cards don't support those odd frequencies, as you have found out.

But it's not been a problem whatsoever for me, and right now NV has the upper hand in efficiency and raw power, though not on price/perf for most midrange cards. Is there a reason you actually need those frequencies?

Thanks for the replies. I can play the "forbidden" file by resampling. If I attempt to play them directly through Foobar 2000 via WASAPI or ASIO instead of the Windows audio mixer I get an "unsupported file type" error. The most common forms of 88.1 and 176.4 kHz files are created when using a Playstation to rip an SACD and convert to PCM. I am trying to eliminate any physical media used for playing digital audio.

I sent a tech support question to AMD. If I can get a definitive answer, I will share.
